ことを課題とする。However, according to the above prior art, when throwing a fly or the like to a target point where a fish is to be thrown, the bending rigidity in the direction in which the fly or the like is thrown and the bending in the lateral direction with respect to the throwing direction. Because of the rigidity and flexibility, the movement direction of the arm that moves the rod moves slightly in the left and right direction with respect to the throwing direction when moving the rod quickly in the direction the angler throws. However, the blur is enlarged due to the elasticity of the fishing rod, and is transmitted to the tip of the rod more largely. Also, when a wind blows from the lateral direction between the target point and the angler reaching the fly, etc., the fishing rod bends to the right or left due to the wind pressure due to the cross wind, and the fly, etc. is likely to deviate left and right from the target point. Become. SUMMARY OF THE INVENTION It is an object of the present invention to provide a fly-fishing fishing rod that more accurately throws fly and the like to a target point.

な材料を使用する。FIG. 1 shows an embodiment of the present invention. The shape is such that the moment of inertia of each section perpendicular to the longitudinal direction of the fishing rod is such that the moment of inertia relative to the vertical axis passing through the center of the section is greater than that relative to the horizontal axis. (A) shows a non-regular polygon, and (b) shows an elliptical cross-sectional shape. "Effects of Embodiment" According to this embodiment, the second moment of area with respect to the vertical axis (yy) is larger than the second moment of area with respect to the horizontal axis (xx). Here, the Young's modulus of the material constituting the fishing rod is E,
Assuming that the second moment of area is I, the bending stiffness is expressed by equation (1). Bending stiffness = E × I (1) Accordingly, if I y is a second moment of area with respect to the vertical axis (yy) and I x is a second moment of area with respect to the horizontal axis (xx), the vertical axis of the fishing rod Flexural rigidity (E × I
y ) will be greater than the bending stiffness (E × I x ) with respect to the horizontal axis. Here, all the sections in the fishing rod longitudinal direction,
Alternatively, in part, when the shape is determined so that the second moment of area with respect to the vertical axis is larger than the second moment of area with respect to the horizontal axis, the bending rigidity with respect to the vertical axis of the fishing rod as a whole becomes greater than the bending rigidity with respect to the horizontal axis. That is, when throwing a fly or the like to a target point where a fish is present, the bending stiffness of the fishing rod in the transverse direction with respect to the throwing direction (the bending stiffness with respect to the vertical axis) is greater than the bending stiffness of the fishing rod in the throwing direction (bending stiffness with respect to the horizontal axis). It can be large and bends sideways. Therefore, when throwing a fly or the like,
When the angler quickly moves the fishing rod in the target direction, the lateral movement of the tip of the rod due to the side movement of the arm and the bending of the fishing rod in the horizontal direction due to the cross wind can be minimized, and the fishing rod can be more accurately thrown to the target point I can carry it. "Other Embodiment" A material is used in which the Young's modulus of the material constituting the fishing rod with respect to the vertical axis is larger than the Young's modulus with respect to the horizontal axis.

る。As described above, according to the present invention, the bending rigidity with respect to the vertical axis can be made larger than the bending rigidity with respect to the horizontal axis with respect to the cross section perpendicular to the longitudinal direction of the fishing rod. Since the lateral bending rigidity in the throwing direction can be made larger than the bending rigidity in the throwing direction, the lateral movement is minimized, and the fly and the like are thrown more accurately and easily to the target point. Can be done.
